 In the end, changing market conditions made a 44-seat airplane like the 428JET inferior to 50 seat aircraft, which have nearly the same operating and procurement costs yet higher profits due to having more seats.This caused the company to cancel the 428JET on August 8, 2000.At the time of cancellation, the aircraft had 39 firm orders with another 88 options (55 of these options could be taken on either the 328JET or 428JET).
